Single frequency interference | Freeview Interference
Tuesday 3 November 2015 2:05AM

So tonight (Mon 2nd Nov), again we lost all channels on com6/ArqB from about 20:30 on both the TV and Humax Freeview PVR. All other channels are showing 100% quality - 85% signal strength.
From looking at these pages, outside of transmission problems, I'm assuming 'single frequency interference' is the cause.
I have checked all connections, and checked the possible problem points suggested.
Local Analogue Interferance;
We don't have a 'Sky Digibox'.
The only 'loop through' is via a Humax Freeview PVR to a digital LG TV, they are also connected via an hdmi cable for normal viewing. The 'loop through' is only used to view the TV when the PVR is recording two programs and we want to watch one that is blocked by recording.
We have a VCR/DVD player connected via a scart lead.
We have a Humax Freesat box connected to the TV via an hdmi cable.
We do not have a games console.

Non-wideband aerial;
We have a 32 bay high gain wide band aerial installed externally above the chimney, aimed as best as is possible at the Selkirk transmitter, there are no line of sight obstructions, there is a signal amplifier in the down lead at the PVR, all cables are copper core/copper shield/copper foil screen and all joints are connected with F connectors. Due to the hills either side of us we are unable to receive signals from Pontop Pike or Chatton without raising the aerial another 7M. Our postcode is TD12 4XN.

Reading what channels we should/shouldn't be able to receive, I note Selkirk is not an 'extended HD' transmitter, we cannot receive the channels mentioned except we do receive Motors TV?
Grateful for any help given.
